Old military styled jewelry

This is a piece of old military styled jewelry found in a bunch of jewelry a friend of mine inherited from her mother. You can see in the first picture that there is a propeller shaped pin at the top and three buttons attached by chains to the pin. It appears to me that the pin would be attached to a lapel or pocket and the buttons would serve as the buttons for a jacket, most likely a women's jacket. It has been suggested it might be sweetheart jewelry which sounds very likely to me. I would like to find out any information on the piece such as age, origin, and potential value. The propeller with wings symbol seems to place it around WWII or prior. The pictures are much better quality then the first post that was deleted. Thanks for looking and any information is appreciated.
